Okay, since Big Jim confirmed my understanding that ATF+3 has a lot of FM in it, the next logical question is:
Wouldn't using 100% Mobil 1 ATF and adding say double the FM (4 ounces) give about the same end result ?
Same question from a different angle: if Mobil 1 makes people loose their 3rd gear syncros because it's too slippery why not make it grippier, instead of switching to a different synthetic fluid (redline mtl) which has more FM, yes, but is thicker and causes more cold weather problems? It's not the low viscosity that causes a loss of the syncro, it's the lack of sufficient friction as I understand it. True?
